Detailed Description

This class provides a meta-data group of actions that are all executed based upon evaluation of a condition (if the condition has been set). If the condition evaluates to true or a condition was never set up, all actions in the list will be executed. A Condition can contain nested conditions nested to any level.

Eg. for menu scripting, Actions is a GlsMenuActionGroup without the condition set (so the name is used). There are 2 nested GlsMenuActionGroups that both have conditions.:

Actions: { // List all actions to be executed

if ( == VALUE1 && ) { // List all actions to be executed

if ( == VALUE3 || > ) { // List all actions to be executed }

// List any more actions to be executed

}

// List any more actions to be executed }

Constructor & Destructor Documentation

GlsMenuActionGroup::GlsMenuActionGroup	(	const std::string &	name,
		GlsMenuDictionary &	dataDict,
		GlsMenuAction::HandlerCont_t &	actionHandlers
	)

Class constructor.

Parameters

name	the name of the group of data items.
dataDict	the menu data dictionary used to evaluate menu data variables
actionHandlers	These are handlers for menu actions passed in by the creator. These are considered local to the menu set.

virtual GlsMenuActionGroup::~GlsMenuActionGroup ( )

virtual

Class destructor.

Member Function Documentation

virtual void GlsMenuData_T< std::string >::Attach ( std::string *& data )

virtualinherited

Attaches an external pointer to the data so that dereferencing the pointer will allow access to the data item's value without performing dictionary lookups and data value retrievals.

bool GlsMenuAction::CanExecute ( std::string & statement ) const

protectedinherited

Determine if there is a condition in front of the action to perform and if so, evaluate the condition and return the result. If there is no condition, true is returned.

void GlsMenuActionGroup::Condition ( const std::string & expression )

Set the logical expression used to determine if the actions should be executed when Execute is invoked.

virtual void GlsMenuActionGroup::Execute ( ) const

virtual

Invoke all actions associated with the instance. Derived classes can override this method to add new action types.

Parameters

dict	data dictionary to use for evaluating action parameters.

Reimplemented from GlsMenuAction.

virtual void GlsMenuData::Inc ( long amount = 1 )

virtualinherited

Increment the data item. Derived classes must override this as the default is a no-op.

Reimplemented in GlsMenuDiscrete_T< T >.

Referenced by GlsMenuSet_T< MenuType_t, DataFactory_t >::IncData().

virtual bool GlsMenuLine::OkToWrite ( )

virtualinherited

Returns false if the string is empty.

virtual std::istream& GlsMenuActionGroup::ReadValue ( std::istream & instr )

virtual

Read attribute dictionary from an input stream.

Parameters

instr input stream to read value from.

Reimplemented from GlsMenuLine.

virtual bool GlsMenuData_T< std::string >::ReferTo ( std::string & data )

virtualinherited

Changes the data item to refer to and use the external variable rather than its own memory. Allows access to the data item's value without performing dictionary lookups and data value retrievals.

static void GlsMenuAction::Register	(	const std::string &	name,
		ActionHandler_t *	handler
	)

staticinherited

Register a handler for a specific action.

Parameters

name	action name
handler	handler for the action

virtual void GlsMenuData_T< std::string >::ResetValueChanged ( )

virtualinherited

Sets the previous value to the current value.

void GlsMenuData_T< std::string >::SetPrecision ( int outputPrecision )

inherited

Allows for setting of precision for floating point numbers. This is the number of digits to be shown after the decimal point.

virtual const std::string & GlsMenuData_T< std::string >::Value ( ) const

virtualinherited

Returns the value of the simulation meta-data.

virtual std::string & GlsMenuData_T< std::string >::Value ( )

virtualinherited

Returns a reference value of the simulation meta-data.

virtual void GlsMenuData_T< std::string >::Value ( const std::string & val )

virtualinherited

Sets the value of the simulation meta-data.

virtual bool GlsMenuData_T< std::string >::ValueChanged ( )

virtualinherited

Determines if the value has changed since the last call to this method.

virtual std::ostream& GlsMenuActionGroup::WriteValue ( std::ostream & outstr )

virtual

Read attribute dictionary from an input stream.

Parameters

instr input stream to read value from.

Reimplemented from GlsMenuData_T< std::string >.
